Protect" to enable the function and this area will be reserved for Video BIOS ROM access only.
Select "Uncached" to disable this function and make this area available for other devices.
Cache Base 0-512K
If enabled, this feature will allow the data stored in the base memory area: block 0-512K to be
cached (written) into a buffer, a storage area in the Static DRM (SDROM) or to be written into L1,
L2 cache inside the CPU to speed up CPU operations. Select "Uncached" to disable this function.
Select "Write Through" to allow data to be cached into the buffer and written into the system
memory at the same time. Select "Write Protect" to prevent data from being written into the base
memory area of Block 0-512K. Select "Write Back" to allow CPU to write data back directly from
the buffer without writing data to the System Memory for fast CPU data processing and operation.
The options are "Uncached", "Write Through", "Write Protect", and "Write Back".
Cache Base 512K-640K
If enabled, this feature will allow the data stored in the base memory area: block 512K-640K to be
cached (written) into a buffer, a storage area in the Static DRM (SDROM) or to be written into L1,
L2 cache inside the CPU to speed up CPU operations. Select "Uncached" to disable this function.
Select "Write Through" to allow data to be cached into the buffer and written into the system
memory at the same time. Select "Write Protect" to prevent data from being written into the base
memory area of Block 512K-640K. Select "Write Back" to allow CPU to write data back directly
from the buffer without writing data to the System Memory for fast CPU data processing and
operation. The options are "Uncached", "Write Through", "Write Protect", and "Write Back".
Cache Extended Memory
If enabled, this feature will allow the data stored in the extended memory area to be cached
(written) into a buffer, a storage area in the L1, L2, L3 cache inside the CPU to speed up CPU
operations. Select "Uncached" to disable this function. Select "Write Through" to allow data to be
cached into the buffer and written into the system memory at the same time. Select "Write
Protect" to prevent data from being written into the extended memory area. Select "Write Back" to
allow the CPU to write data back directly from the buffer without writing data to the System
Memory for fast CPU data processing and operation. The options are "Uncached", "Write
Through", "Write Protect", and "Write Back".
Discrete MTRR Allocation
If enabled, MTRRs (-Memory Type Range Registers) are configured as distinct, separate units
and cannot be overlapped. If enabled, the user can achieve better graphic effects when using a
Linux graphic driver that requires the write combining configuration with 4GB or more memory.
The options are Enabled and Disabled.
PCI Configuration
Access the submenu to make changes to the following settings for PCI devices.
Onboard GLAN1/GLAN2 (Gigabit- LAN)
Enabling this option provides the capability to boot from GLAN. The options are Disabled and
Enabled.
Reset Configuration Data
If set to Yes, this setting clears the Extended System Configuration Data- (ESCD) area. The
options are Yes and No.
Frequency for PCIX
This option allows the user to change the bus frequency for the devices installed in the slots
indicated. The options are Auto, PCI 33 MHz, PCI 66 MHz, PCI-X 66 MHz, PCI-X 100 MHz, and
PCI-X 133 MHz.
